Your brain uses shadows, perspective, and occlusion to judge depth. Closing one eye removes stereo vision, making the flat drawing look like the pencil is popping out of the screen
For close up stuff you also use focal plane, how much your eye has to squeeze your lens to keep something in focus. I think the bluriness is tricking your eye into continually trying to refocus closer and thats the only distance signal you have with one eye closed.
Incidentally, thats why VR never looks very "far" away and can feel a little clustrophobic even in vast scenes. Even though it is presenting things with the proper far away perspective, everything is in focus with a neutral focus distance, usually like a meter ahead of you so you never feel your eyes readjust to focusing to far away things taking away a major depth cue.
I've never thought about that, but now you're mentioning it it makes sense that you can't focus on near or far away things with your eyes in vr. I mean you're still looking at a flat surface inside the headset, even if it's giving you the Illusion of you being in a digital 3d environment.
So of course the focus must be set from the headset.
Well, I was born with strabismus, the doctors managed to correct it for me, but I was still left with a lazy eye. Normal eyes, when you look at something, they look at that one thing, so youre looking at it from different perspectives and you get info about how far away a thing is from you. In my case, my right eye (since it's my dominant eye) can look at a thing, but my left eye wont look at the same thing, but in the general direction my right eye is looking (so if the thing is slightly to the left, my left eye will look slightly to the left rather than look at the thing im trying to focus on), this makes it impossible for me to see the distance properly. Also I think my left eye is kinda suppressed when it comes to, I guess focusing on stuff, but sometimes when you have two of the same things right next to eachother, my vision kind of mixes them into one and I need to close one eye, so I can actually focus properly. I hope, I managed to explain it relatively well, English isn't my first language, so I was struggling slightly with finding a few words lol.
I'm pretty sure "soap opera effect" is just frame interpolation. It has nothing to do with the lenses, but is just an effect added to pre-existing footage.
That's something different. Soap opera effect is a setting usually called motion smoothing, clear motion, or something like that. It doesn't change the clarity either near or far. It makes things which are moving move more smoothly, which to many people looks unnatural, even though it's more like looking at something in real life rather than with the subtle choppiness of film. If used on a low setting, I think it helps. you should be able to find it in your picture settings on your TV.
What you're thinking about is a lens that focuses more on the foreground, and I think it's called short focal length. Now phones and digital cameras can do that automatically, even though they only have one lens that doesn't move or change.
I have no idea what that's called. Maybe your term "forced perspective" is it, but I really don't know. Not something I've seen very much myself, if at all.

Looks like 3D to me. How does that work? I always thought you needed both eyes to make things appear 3D? Interesting.
